Is it possible to properly fit the MP 3,1 logic board into a 1,1 chassis and to use the RAM and CPUs of the MP 1,1? Basically I want to only upgrade the logic board in my MP 1,1 to MP 3,1, but keep all the other parts the same old ones to make it a true 64bit. Why? Because it would cost less than $200 to go up a little and use an otherwise perfect machine for a little longer. (I don't mind to alter the case a little bit if it has to.) Has anyone ever done it?
